The remainder of this command documentation specifies the " "full command signature and details of the search process. Project " "maintainers wishing to provide a package to be found by this command " "are encouraged to read on.\n" "The command has two modes by which it searches for packages: " "\"Module\" mode and \"Config\" mode. " "Module mode is available when the command is invoked with the above " "reduced signature. " "CMake searches for a file called \"Find.cmake\" in " "the CMAKE_MODULE_PATH followed by the CMake installation. " "If the file is found, it is read and processed by CMake. " "It is responsible for finding the package, checking the version, " "and producing any needed messages. " "Many find-modules provide limited or no support for versioning; " "check the module documentation. " "If no module is found the command proceeds to Config mode.\n" "The complete Config mode command signature is:\n" " find_package( [version] [EXACT] [QUIET]\n" " [[REQUIRED|COMPONENTS] [components...]] [NO_MODULE]\n" " [NAMES name1 [name2 ...]]\n" " [CONFIGS config1 [config2 ...]]\n" " [HINTS path1 [path2 ... ]]\n" " [PATHS path1 [path2 ... ]]\n" " [PATH_SUFFIXES suffix1 [suffix2 ...]]\n" " [NO_DEFAULT_PATH]\n" " [NO_CMAKE_ENVIRONMENT_PATH]\n" " [NO_CMAKE_PATH]\n" " [NO_SYSTEM_ENVIRONMENT_PATH]\n" " [NO_CMAKE_BUILDS_PATH]\n" " [NO_CMAKE_SYSTEM_PATH]\n" " [CMAKE_FIND_ROOT_PATH_BOTH |\n" " ONLY_CMAKE_FIND_ROOT_PATH |\n" " NO_CMAKE_FIND_ROOT_PATH])\n" "The NO_MODULE option may be used to skip Module mode explicitly. " "It is also implied by use of options not specified in the reduced " "signature. " "\n" "Config mode attempts to locate a configuration file provided by the " "package to be found. A cache entry called _DIR is created to " "hold the directory containing the file. " "By default the command searches for a package with the name . " "If the NAMES option is given the names following it are used instead " "of . " "The command searches for a file called \"Config.cmake\" or " "\"-config.cmake\" for each name specified. " "A replacement set of possible configuration file names may be given " "using the CONFIGS option. " "The search procedure is specified below. Once found, the configuration " "file is read and processed by CMake. Since the file is provided by the " "package it already knows the location of package contents. " "The full path to the configuration file is stored in the cmake " "variable _CONFIG." "\n" "If the package configuration file cannot be found CMake " "will generate an error describing the problem unless the QUIET " "argument is specified. If REQUIRED is specified and the package " "is not found a fatal error is generated and the configure step stops " "executing. If _DIR has been set to a directory not containing " "a configuration file CMake will ignore it and search from scratch." "\n" "When the [version] argument is given Config mode will only find a " "version of the package that claims compatibility with the requested " "version (format is major[.minor[.patch[.tweak]]]). " "If the EXACT option is given only a version of the package claiming " "an exact match of the requested version may be found. " "CMake does not establish any convention for the meaning of version " "numbers. " "Package version numbers are checked by \"version\" files provided by " "the packages themselves. " "For a candidate package confguration file \".cmake\" the " "corresponding version file is located next to it and named either " "\"-version.cmake\" or \"Version.cmake\". " "If no such version file is available then the configuration file " "is assumed to not be compatible with any requested version. " "When a version file is found it is loaded to check the requested " "version number. " "The version file is loaded in a nested scope in which the following " "variables have been defined:\n" " PACKAGE_FIND_NAME = the name\n" " PACKAGE_FIND_VERSION = full requested version string\n" " PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0\n" " PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0\n" " PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0\n" " PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0\n" " PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4\n" "The version file checks whether it satisfies the requested version " "and sets these variables:\n" " PACKAGE_VERSION = full provided version string\n" " PACKAGE_VERSION_EXACT = true if version is exact match\n" " PACKAGE_VERSION_COMPATIBLE = true if version is compatible\n" " PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version\n" "These variables are checked by the find_package command to determine " "whether the configuration file provides an acceptable version. " "They are not available after the find_package call returns. " "If the version is acceptable the following variables are set:\n" " _VERSION = full provided version string\n" " _VERSION_MAJOR = major version if provided, else 0\n" " _VERSION_MINOR = minor version if provided, else 0\n" " _VERSION_PATCH = patch version if provided, else 0\n" " _VERSION_TWEAK = tweak version if provided, else 0\n" " _VERSION_COUNT = number of version components, 0 to 4\n" "and the corresponding package configuration file is loaded. " "When multiple package configuration files are available whose version " "files claim compatibility with the version requested it is unspecified " "which one is chosen. " "No attempt is made to choose a highest or closest version number." "\n" "Config mode provides an elaborate interface and search procedure. " "Much of the interface is provided for completeness and for use " "internally by find-modules loaded by Module mode. " "Most user code should simply call\n" " find_package( [major[.minor]] [EXACT] [REQUIRED|QUIET])\n" "in order to find a package. Package maintainers providing CMake " "package configuration files are encouraged to name and install " "them such that the procedure outlined below will find them " "without requiring use of additional options."
